Turner Motorsport E9X Heavy Duty Billet Aluminum Differential Cover Kit

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing, this diff cover can handle anything you throw at it. Not only is it an absolute masterpiece, but this billet diff cover checks all the boxes for the features needed. Reinforced mounting ear for strength and stability. The mounting ear is unified with the one-piece billet cover and features added material for the highest durability possible. This diff cover is cool, literally; the entire construction was designed with optimized cooling in mind. External fins are strategically placed on the rear face, bottom, and between the mounting ears of the cover, serving as effective heat sinks for optimal heat dissipation. This ensures stable temperatures, promoting longevity for both the fluid and your differential. Additionally, the internal design ensures continuous oiling and lubrication of the ring gear, maintaining its stability and preventing fatigue by controlling heat more effectively. An internal baffle at the cover's corner helps maintain proper pressure and prevents cavitation.

All of the OEM features were retained along with the upgrades. The drain and fill plugs on the diff cover are upgraded to -6AN using the provided high-pressure fittings with replaceable O-rings. The drain and fill plugs can now be used for an external oil cooler, allowing you to further expand the fluid capacity for optimized cooling and service intervals. To keep an eye on things from the driver's seat is a 1/8 NPT provision for temp sensors; this product from Turner has you covered at every turn.

Upgrading to the Turner Billet Differential cover gives you the strength you need to push your car to its limits without worrying about snapping a diff mount from clutch kicking or other shocks to the drivetrain. In addition to its enhanced strength, this differential cover includes numerous other upgrades and conveniences. These include improved cooling and lubrication for the ring gear, upgraded fill and drain plugs, and the option to expand an external oil cooler for extreme motorsport usage. Designed to complement both upgraded daily drivers and extensively modified track cars, it also offers a visually appealing design.

FEATURES

• Reinforced mounting ear for strength and stability
• 16% increased fluid capacity
• External fins on the back side, bottom, and mounting ear on the casing for maximum cooling and consistent fluid temps
• Removable air duct to direct air across the cooling fins for even more temperature control
• Optimized internal design to keep fluid consistently on the ring gear
• Integrated breather to prevent cavitation by venting the appropriate amount of pressure being built up in the diff housing
• -6AN ports to incorporate the use of a differential cooler - this increases capacity and lowers temps allowing for extended fluid change intervals
• 1/8 NPT fitting for the use of a temp sensor to monitor fluid temperature
